We have implemented SSO and it was working fine, but after applying the latest support packs
we have noticed that going from ESS Applications (ITS based) to Webdynpro in SAP Portal stops with logon screen and the message: No switch to HTTPS occurred, so it is not secure to send a password.
There is no any errors produced in the logs (WP log, java logs). The only what visible in HTTP trace files that
ITS issues command "logoff" and therefore the login screen appears with the message "No switch to HTTPS occurred..."
The problem only happens when switching from ESS ITS based applications to Webdynpro applicaions inside the portal.
It does not happen when switching from Webdynpro to ESS (ITS). ALL SSO ceritificates are fine as we can work with Webdynpro applications or ESS applicatons without any issues, but as soon as we switch from ESS (ITS) to Webdynpro the error occures.
I have logged the call with SAP, and after 10 days of investigating the logs and not finding any errors, SAP replies:
"Please read through the note 870126 that we can't support these services on the integrated ITS, as they have been designed for the external ITS instead."
Any help is much appreciated.
Thanks and regards
